A general term for the arsenic analogues of ammonium and phosphonium salts, (H 4 As) + X- and their substituted derivatives (R 4 As) + X- (X is a monovalent anion, R is an alkyl or aryl group). The reaction of arsine R 3 As with an alkyl halide R'X gives tetraalkylarsonium halide salts (R 3 R'As) + X- , which can be further reacted with silver hydroxide to give tetraalkylarsonium hydroxides. The reaction of tetraalkyl (or aryl)arsonium halide with an organolithium compound gives arsorane R 5 As. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
アンモニウム塩やホスホニウム塩のヒ素類似体である(H4As)+X-およびその置換体(R4As)+X-の総称(Xは1価の陰イオン,Rはアルキル基またはアリール基)。アルシンR3Asとハロゲン化アルキルR′Xとの反応により,ハロゲン化テトラアルキルアルソニウム塩(R3R′As)+X-が合成できる。これをさらに水酸化銀と反応させれば水酸化テトラアルキルアルソニウムとなる。ハロゲン化テトラアルキル(あるいはアリール)アルソニウムと有機リチウム化合物との反応によりアルソランR5Asが合成できる。
